I mmvrox. VICTOR E.ANDERSO N ATTORNEYS Patented Dec. 19, 1944 UNITED STATES PATENT OFFICE COMBINATION STORM SASH'AND SCREEN STRUCTURE 3 Claims.

This invention relates generally to storm sash and refers more particularly to an improved storm sash and screen combination.

One of the essential objects of the invention is to provide a combination of the type mentioned having glass and screen inserts which may be readily and easily removed andinterchanged whenever desired from the inside of the building upon which they are mounted. Thus it is unnecessary to employ skilled labor, ladders and tools as in the past when inserts are removed,

interchanged or replaced.

Another object is to provide an improved com bination wherein easy and efficient ventilation may be readily obtained without swinging the entire storm sash outward relative to its supporting frame or providing slots or openings in the rails of the sash as heretofore. Moreover, my structure avoids the use of slidable inserts which require guidesand other added fixtures that increase the cost thereof.

Another object is to provide a storm sash and screen combination that is constructed in such a way that it may provide an indirect'ventilation through the upper portion of an ordinary sliding double sashwindow structure when the upper sash thereof is lowered, and will cooperate with th lowered sash of the window structure to effectively prevent rain, snow, sleet, etc., from entering the building while being ventilated.

Another object is to provide a combination of the type mentionedwherein only the lower portion thereof is adapted to be operated or moved. The upper portion is rigid or fixed. Thus, the general mechanical difficulties now existing in other forms of storm sash are reduced and a better air-tight storm structure is provided.

Another object is to provide a storm sash and screen combination wherein the glass and screen inserts at the lower portion thereof are interchangeable and are substantially similar in size or area to the size of the ordinary window. Heretofore when separate storm sash and screens in their entirety were interchanged, a tight-fit with the ordinary window frame was not always obtained because window frames of like size in a home or building are not or do not always remain square or close enough to their exact size to permit separate storm sash and screens to be interchanged and obtain a tight fit. With my construction the frame of the storm sash remains fitted to the window frame and only the lower glass insert and screen insert therefor are interchanged. Hence a tight fit is assured because ,the inserts are interchanged accurately and the window frames.

Another object is to provide a combination wherein yieldable elements, preferably in the form of coil springs, are employed for holding the inserts in proper assembled position relative to the frame. of the combination. Actually these springs serve as flexible hangers and hinge elements for the inserts when swung outwardly relative to the frame.

Another object is to provide a combination that is simple in construction, economical to manufacture, easy to install, and efficient in operation.

Other objects, advantages and novel details of construction of this invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings, wherein:

Figure 1 is a sectional perspective view of a storm sash and screen combination applied to an ordinary sliding double sash. window structure and showing the upper sash in lowered position permitting indirect circulation of air from the outside through the screen insert and upwardly over the lowered sash to the inside of the window frame. a

Figure 2 is a front elevation of a storm sash and screen combination embodying my invention;

Figure 3 is a rear elevation of the combination; Figure 4 is an edge elevation of the combination when a glass insert is employed and showing the insert swung outwardly and held in such position by a hook and eye, the window frame being in section;

Figure 5 is a vertical sectional view taken substantially on the line 5-5 of Figure 2;

Figure 6 is a cross sectional view taken substantially on the line 66 of Figure 2;

Figure 7 is a detail view of the glass insert;

Figure 8 is a detail view of the screen insert.

Referring now to the drawings, A is the frame, and B and C, respectively, are the vertically sliding glass sash of an ordinary sliding double sash window of a building such as a dwelling.

- the respective inserts in assembled, relation to the frame, and fasteners 15 and |6,..respectively. for

bottom rails l1 and I8, respectively, side rails l9 and 20, respectively, and an intermediate cross rail or bar 2| rigidly secured together. A pane 22 of glass is mounted within the opening 23 bounded by the rails l1, I9, 20 and 2| and constitutes a fixed or rigid closed upper portion of the combination, while framed glass and screen inserts II and [2, respectively, may be used alternately in the space 24 bounded by the rails 2|, I9, 20 and I8 and constitute exchangeable lower portions of the combination.

Preferably the lower edge of the cross rail 2| is provided throughout its length between the side rails 19 and 20 with a downwardly opening channel shaped groove 26 constituting a fulcrum for a transversely extending rib 21 on the upper edge of each insert II and I2, respectively, while the side rails. l9 and 20, respectively, and bottom rail l8 of the frame are provided substantially flush with their forward faces with inwardly extending lateral flanges 3|, 32 and 33, respectively, that constitute abutments for outwardly projecting lateral flanges 34, 35 and 36, respectively, of the inserts II and I2.

Upon the inner face of the side rails 31 and 36, respectively, of-each insert II and I2, near the top rail 39 thereof are hooks 40 and 4| which are adapted to be engaged by the lower ends of the coil springs I3 and I4 anchored at their upper ends upon the inner faces of the side rails I9 and of the frame H1 at points adjacent the intermediate cross rail 2|. These springs l3 and I4 serve the dual purpose of flexible hangers and hinges for the inserts II and I2 so that the inserts will be maintained in proper assembled relation to the frame l0, especially the intermediate cross rail 2| thereof, regardless of in the intermediate cross rail 2| of the frame so that each insert may swing in the groove 26 from closed position to the outwardly inclined position illustrated in Figure 4.

At the bottom of each insert, preferably on the inner face of the lower rail 42 thereof, are two rotatable fasteners I5 and l6 which may be turned by hand about their pivots into engagement with the inner surface of the lower rail I8 of the frame III, as illustrated in Figure 2, to hold the respective inserts in closed position. When in this position the lateral flanges 34, and 36, respectively, of the respective inserts overlap and fit snugly against the lateral flanges 3|, 32 and 33, respectively, of the frame ID to pro vide an air-tight joint between the parts. If desired, one or more suitable grooves 43 may be provided in the inner surface of the bottom rail 42 of each insert to serve as a finger recess when swinging the respective inserts outwardly.

Each insert II and I2 is a complete unit having a rigid frame 50 of substantially square configuration. The insert contains a glass pane 5|, while the insert l2 contains wire mesh or screen material 52. Preferably the frames 56 of the inserts and the main frame ID of the combination are formed of wood, however it is apparent that any suitable material may be employ d as desired. Likewise the shape or configuration of the respective parts may be varied as desired. The essence of the invention resides in the provision of a storm sash having a rigid closed upper portion and removable interchangeable glass and screen inserts such as H and I2, respectively, in the lower portion, said inserts being held in assembled relation with the frame ID by springs such as l3 and [4 that serve as yieldable hanger and hinge elements for said inserts.

The groove 26 in the lower edge of the cross rail 2| and the engaging rib 21 on each insert not only cooperate to provide a simple hinge assembly for the inserts but also permit quick and easy removal of the inserts from the main frame Ill. Due to this construction such interchange of inserts or removal thereof may be easily effected from inside the building upon which the combination is mounted. Moreover, the cross rail 2| of the main frame |0 serves as a bottom frame member for the upper fixed glass pane 5| as well as a hinge or fulcrum element for the lower removable inserts II and I2, respectively.

In practice the main frame H) of the storm sash combination may fit against the usual blind stops between the side uprights of the ordinary sliding double sash window frame of a dwelling or other building, however it isapparent that such frame may be mounted upon the outer face of the window frame in any suitable manner to provide a tight storm sash connection with the window frame. Preferably the main frame l0 of the storm sash combination may be attached to the window frame by screws or may be hung with regular storm sash or screen hangers the same as conventional storm sash or screens are hung. In fact, the storm sash and screen combination is such that it could be used alone as the main window structure in a building, especially in temporary housing projects of the type now being carried out for factory workers.

' sired manner to permit the inserts H and I2 to be alternately used in the frame Ill.

When it is desired to remove or interchange the inserts H and I2, the insert in the frame It is swung outwardly to clear the lower or bottom rail |8 of the main frame and then is pressed or pulled downwardly to remove or withdraw the rib 21 from the groove 26. Then the insert is allowed to move upwardly in substantially parallel relation to the main frame to relieve tension on the springs I3 and M. When in this relieved position the lower ends of the springs I3 and I4 may be readily disengaged from the hooks 40 and 4| on the main frame so that the insert may be removed entirely from the combination. To replace the insert or to substitute the other insert in the frame NJ, the reverse procedure is followed, i. e., the lower ends of the springs l3 and M are first engaged with the hooks 40 and 4| on the insert, then the latter is pressed or pulled down so that the rib 21 may be engaged with the groove 26 in the cross rail 2|. The springs l3 and I4 will then automatically move the insert upwardly into assembled position with the frame.

Should it be desired to provide direct ventilationv when the glass insert H is mounted within the frame ID of the combination, the lower sash of the ordinary window may be raised and the glass insert may be swung outwardly and held in its outermost position by a hook 60 and eye 6|. Should it be'desired to provide indirect rain. snow, sleet. etc,

v inserts in a verv few minutes.

ventilation when either of the inserts are employed, the upper sash of the ordinary window may be lowered beside the lower sashso that air may enter-the lower ortion of the storm sash combination either through t e opening therein provided by the outwardly swung glass insert II or through the screen insert l2, as illustrated in Figure 4. Such air will then flow upwardly over the top edge of the lowered u per window sash as illustrated in Figure 1 to the interior of the bu lding. Thus, when both window sash are in lowered position as illustrated in Figure 1, the air from the outside may enter the building. but is prevented from entering by the fixed upper glass portion 22 of the storm combinati n and by the lowered sash of the window structure.

T us, from the fore oing, it will be apparent that I have provided an eflicient all weather and all year protection which may be readily ap lied at low installation cost. In fact. the combination is so well constructed and easy to operate that anv unskilled pers n may nterchange the The convenience of the change-over and the small storage space reouired for the inserts not being used are important factors of my construction. Moreover, the change-over. i. e.. the interchanging of inserts can always be made from inside the building, hence ladders, tools, etc., are unnecessary. It should also be noted that the glass pane 5| and wire mesh 52 in the inserts I I and i2, res ectively. are held in place by wood moldin s such as 1'). hence puttv and the like has also been dispensed with entirely and a ture is provided.
